Re: [RCSE] Frequency Control / safety
Matthew, It is not illegal to use a transmitter to fly your plane. There is no restriction other than local ordinances that prevent you from flying and operating your transmitter. Does not matter where you fly, from a club field to a local park. As long as you are using legal channels you are allowed. The illegal act is when you intentionally destroy property or cause harm by operating your equipment. For example, if you knowingly shoot someone down in order to destroy their plane. A well known example of this occured in California with some ginat scale racing. The offender (sitting in his car) was caught. Anyway, as a user of the equipment you are responsible for its proper use. If while at your local slope your freq is used you cannot turn on to clear your channel! Nor can you operate your equipment knowingly to prevent someone else from operating theirs. Basiclly you cannot tell someone else to go home as you were there first and on your freq. They have every right to operate as you do. The most problematic situation is the rogue flier. This includes people flying HL in the backyard, IMAC at their local school, or even the famous park flier. If they have no knowledge of a freq conflict with another person then they are not commiting a crime as they are not intentionally causing damage or injury directly. Though during a cival trial they could be found responsible for any damage caused by their actions even though legally they did not comit a crime.

Re: [RCSE] Frequency Control / safety
The illegal act is when you intentionally destroy property or cause harm by operating your equipment. Knowingly doing it, is way different than negligently doing it. If I just fly on a frequency, there is no intent to cause damage (negligence maybe, but not criminal). if you tell me that you are on a frequency, I have every right to say so, am I. If you fly, you fly your plane at your own risk. How much damage can it do? Negligence is proportionate. I fly my plane at my own risk. Once you are aware that I fly on a frequency, the onus is on YOU to prevent damage, not me. Basiclly you cannot tell someone else to go home as you were there first and on your freq. They have every right to operate as you do. Sure you can. If I am flying on a frequency, I have no duty, legal or otherwise, to give you a turn. Your option, is to go away, or change frequencies. the politeness police can come talk to me, but neither the FCC, or the police give a rats a**. No laws are broken. As secondary users, you have to accept ALL forms of interference, including other legal users. The most problematic situation is the rogue flier. This includes people flying HL in the backyard, IMAC at their local school, or even the famous park flier. If i live across from a club field, and fly my parkflier in my front yard, all i have to do is to tell the club that i use XX frequency, and then they have the duty to see that none of their planes cause damage. the problem, is that if i am flying my park flyer a hundred feet from my your radio a block away won't affect my plane, but my radio will affect yours, because you fly at a greater distance. Once you put a plane into the air, knowing that there is a high probability of interference, you are negligent. Plaintiff were you aware that the gentleman a block away flies a plane on the same frequency as you? Defendant yes Plaintiff but you decided to fly anyway Defendant yes' at this point, you have admitted liability. get out the checkbook. you might be able to pin some on the guy with the park flier, but nothing will get you off (which is the point). to pin any on the parkflier, you would have to be able to prove that he caused the shoot down, which would be really difficult to do.

Dont get your feathers ruffled. All I said was that just because you choose to fly overpriced, pre-build, moulded ARFS does not give you any frequency advantage.

RE: [RCSE] Frequency Control / safety
I switched to the ham band almost ten years ago just because I was tired of sharing freqs when I was at the slopes. At the moment, I'm the only one on the slopes that is *legally* using the ham freqs. But that doesn't stop me from asking others what channels they are on and informing others of my channel. One drawback I can think of in having the ham band channels is that rx's are a little more expensive than the 72 mhz counterparts. But at least hams have the legal exclusive rights to the 50 53 mhz r/c channels. Until better frequency management technology is implemented in our hardware, we will always be in danger of being shot down by others who are clueless or don't give a rip.

I have one in the laptop I'm using now. The card itself is a PCMCIA and weighs, oh, less than half an ounce. And it speaks TCP/IP. If we had real packets, we could send/receive anything to and from the ship with redundancy, frequency wouldn't especially matter, you could encrypt/decrypt your signal, and you could have a web server that sent out a webpage that told altitude, attitude, whatever (not that a web page would be a good idea; something streaming would be way better). And I bet it could be done for the same prace as radios now. The card in my computer cost $90. If it was integrated into a whole radio, eh, maybe it would cost a little more. But you could use an embedded chip onboard to decrypt and parse and talk to the servos. But we don't do this because it's not where we're coming from. We're coming from free flight. We want to control our models, so we attach lines, then radios. Then we want to mix the radio signal. It's an evolutionary process, but every so often a revolution's a good idea.

It would be a bit of effort, but would probably pay off to some extent in the long run: Make up some professional-looking (i.e. NOT handwritten) single-page Tip Sheets. We'll call them that for now, if for no other reason than I can't think of anything fancier. Briefly and simply explain the issue of frequency conflict/control. Include the concept of pin boards and stress the importance of ASKING FOR HELP at fields, if one is uncertain of the goings-on. Print these on brightly-colored paper (the fluorescent reds or greens come to mind). Leave a stack of 100 or so at all the local shops...one could enlist the help of a couple of the local clubs with the task. Talk to the manager at each of the stores and try to get them to agree to include one of these sheets with EVERY radio and/or flying package sale. Stress the importance of the issue with him/her, that we're trying to be proactive with a real problem. Visit the shop(s) once a month or as necessary to keep the flyers stocked and talk to the shop personnel. This won't get everyone and maybe it's already been tried to no avail. You may also get a cold reception at some places, but it could work. You might also pick up some new talent in the process. Just thinking out in public here...opinions?

Re: [RCSE] Frequency Control / safety
802.11 (usually known as AirPort) give 11 megabit/sec (about 100k). I have one in the laptop I'm using now (Monkey King) Your network is using 802.11b -- WiFi in today's parlance (its what Apple uses in their AirPort products). Its not going to work too well to control a model since the range is only about 150'. It works quite well despite having to share the band with microwave ovens, cordless phones and other wireless devices. I'm using a newer technology in this computer -- 802.11a -- which uses a higher frequeny link and can theorectically deliver up to 54MBits/sec. Even if it did have the range -- and it could, because we can transmit with significant power at the high end of the band -- its not reactive enough to be safe for a flying model. If the link dropped it could take several seconds to reaquire it, time enough to lose the plane. The idea's good, though. We should be able to do something with the current radio band using commonly available and very inexpensive processors. Our requirements are very modest, in the tens of bits per second. I suppose nothing's been done because of product inertia and regulatory considerations. We should push manufacturers. They're flooding the market with R/C toys -- park fliers -- which are a risk to us all. They need to close the loop so we can all fly without fear.

I believe that hams the government are the only authorized users of the 50-54 MHz band, and most hams will stick to the voluntary bandplans so I think you are pretty safe if you are on those bands.
